Lakshman Achuthan ECRI Today's new release of the publicly available data from the Economic Cycle Research Institute (ECRI) puts its Weekly Leading Index (WLI) at 130.8, unchanged to one decimal place from the previous week. The WLI annualized growth indicator (WLIg) is at -3.9, down from -3.3 the previous week. This is its lowest level since February 2012.

2015 Outlook

Lakshman Achuthan made a recent appearance (December 24th) on Al Jazeera TV discussing the company's outlook for the US economy in 2015 (view the interview here). Despite improvements in GDP and jobs data, Achuthan takes a cautious view. Among other things, he points out that latest year-over-year GDP growth rate of 2.7% (a more intuitive metric than the latest quarterly annualized rate of 5.0%), has happened before since the end of the last recession ... only to slide back to lower levels. He identifies US manufacturing as a potentially weak area in 2015 as result of the global economic slowdown.

ECRI has been at the center of a prolonged controversy since publicizing its recession call on September 30, 2011. The company had made the announcement to its private clients on September 21st. ECRI's cofounder and spokesman, Lakshman Achuthan, subsequently forecast that the recession would begin in Q1 2012, or Q2 at the latest. He later identified mid-2012 as the start of the recession. Over the past two years he has been a frequent guest on the likes of CNBC and Bloomberg TV. He subsequently adjusted the company's position, identifying the recession's "epicenter" as the half-year spanning Q4 2012 and Q1 2013.

The ECRI Indicator Year-over-Year

Below is a chart of ECRI's smoothed year-over-year percent change since 2000 of their weekly leading index. I've highlighted the 2011 date of ECRI's original recession call and the hypothetical July 2012 business cycle peak, which the company previously claimed was the start of a recession. I've update the chart to include the "epicenter" (Achuthan's terminology) of the hypothetical recession.

For a better understanding of the relationship of the WLI level to recessions, the next chart shows the data series in terms of the percent off the previous peak. In other words, a new weekly high registers at 100%, with subsequent declines plotted accordingly.

As the chart above illustrates, only once has a recession ended without the index level achieving a new high -- the two recessions, commonly referred to as a "double-dip," in the early 1980s. Our current level is still off the most recent high, which was set back in June of 2007. We've exceeded the previously longest stretch between highs, which was from February 1973 to April 1978. But the index level rose steadily from the trough at the end of the 1973-1975 recession to reach its new high in 1978. The pattern in ECRI's indictor is quite different, and this has no doubt been a key factor in their business cycle analysis.

The WLIg Metric

The best known of ECRI's indexes is their growth calculation on the WLI. For a close look at this index in recent months, here's a snapshot of the data since 2000.

Now let's step back and examine the complete series available to the public, which dates from 1967. ECRI's WLIg metric has had a respectable record for forecasting recessions and rebounds therefrom. The next chart shows the correlation between the WLI, GDP and recessions.

ECRI's weekly leading index has become a major focus and source of controversy ever since September 30, 2011, when ECRI publicly announced that the U.S. is tipping into a recession, a call the Institute had announced to its private clients on September 21st. Here is an excerpt from the announcement:

Early last week, ECRI notified clients that the U.S. economy is indeed tipping into a new recession. And there's nothing that policy makers can do to head it off. ECRI's recession call isn't based on just one or two leading indexes, but on dozens of specialized leading indexes, including the U.S. Long Leading Index, which was the first to turn down — before the Arab Spring and Japanese earthquake — to be followed by downturns in the Weekly Leading Index and other shorter-leading indexes. In fact, the most reliable forward-looking indicators are now collectively behaving as they did on the cusp of full-blown recessions, not "soft landings." (Read the report here.)

Year-over-Year Growth in the WLI

Triggered by another ECRI commentary, Why Our Recession Call Stands, I include a snapshot of the year-over-year growth of the WLI rather than ECRI's previously favored method of calculating the WLIg series from the underlying WLI (see the endnote below). Specifically the chart immediately below is the year-over-year change in the 4-week moving average of the WLI. The red dots highlight the YoY value for the month when recessions began.

The WLI YoY has gone negative at -0.4, its first negative print since August 2012. While this is higher than the onset of five of the seven recessions in the chart timeframe, it is close to the -0.9% at the start of the last recession.

Additional Sources for Recession Forecasts

Dwaine van Vuuren, CEO of RecessionAlert.com, and his collaborators, including Georg Vrba and Franz Lischka, have developed a powerful recession forecasting methodology that shows promise of making forecasts with fewer false positives, which I take to include excessively long lead times, such as ECRI's September 2011 recession call.

Here is today's update of Georg Vrba's analysis, which is explained in more detail in this article.

Note: How to Calculate the Growth series from the Weekly Leading Index

ECRI's weekly Excel spreadsheet includes the WLI and the Growth series, but the latter is a series of values without the underlying calculations. After a collaborative effort by Franz Lischka, Georg Vrba, Dwaine van Vuuren and Kishor Bhatia to model the calculation, Georg discovered the actual formula in a 1999 article published by Anirvan Banerji, the Chief Research Officer at ECRI: " The three Ps: simple tools for monitoring economic cycles - pronounced, pervasive and persistent economic indicators."
